MisterWGT once stated that they have shot second pin positions for each course, and for KIA, they went an extra mile to produce an additional set from other pictures.
In the Good Olde Days, they would publish "second sets" between the new courses, giving us an incentive to try out the new positions and to adapt the individual course management. The last one that I remember is Merion which happened an unusually short timespan from the course's publication.
Since then, nothing. Not an announcement, no novelty. Apparently, they cut the budgets for that :(
